If the Participant initially elected to be paid upon the earlier of (A) Separation from Service following Retirement or (B) an identified and specific date that is at least three (3) years after the date the deferral agreement was effective, then if payment has not already been made or commenced, his distribution shall be made in a lump sum payment no later than ninety (90) days after the date of his Separation from Service.

an identified and specific date that is at least three (3) years after the date the deferral agreement was executed; or

the earlier of (A) Separation from Service or (B) an identified and specific date that is at least three (3) years after the date the deferral agreement was executed.

The amount a Participant elects to defer in accordance with Article 3 shall be credited to the Participant’s Account at the time the amount subject to the deferral election would otherwise have been payable to the Participant but for his deferral election. The Administrator will establish and maintain such other accounts and records as it determines, in its discretion, to be reasonably required or appropriate to discharge its duties under the Plan.

Investment Options. The amount credited to a Participant’s Account shall be treated as invested in the investment options as designated for this purpose by the Administrator. Such investment options may be different for Eligible Employees, Section 16 Officers and Directors, as determined by the Administrator in its discretion.

Notwithstanding the foregoing or any provision of the Plan to the contrary, if otherwise provided pursuant to a Company plan or program for which a benefit has been deferred under the Plan, a Participant may be subject to certain “claw back” or forfeiture of benefits in certain circumstances, in which case a Participant’s Account may be reduced in an amount necessary to satisfy such “claw back” or forfeiture.

Death. Notwithstanding any prior election regarding the form or timing of his distribution, the balance or remaining balance credited to a Participant’s Account shall be paid to his Beneficiary in a single lump-sum cash payment within ninety (90) days following the Participant’s death. If multiple Beneficiaries have been designated by the Participant, each Beneficiary shall receive a single lump-sum cash payment of his specified portion of the Participant’s Account balance within such ninety (90) day period. If the Participant has not specified percentages for multiple Beneficiaries, his Account will be divided and distributed to them on a per capita basis.

Disability. Notwithstanding any prior election regarding the form or timing of his distribution, the balance or remaining balance credited to a Participant’s Account shall be paid to the Participant in a single lump-sum cash payment within ninety (90) days following the date the Participant is determined to be Disabled.

Method and Timing of Distributions. Subject to Sections 7.3 and 7.4, distributions under the Plan shall be made at the time and in the manner provided in Section 3.6. If allowed by the Administrator, a Participant may elect to further delay the payment date for a minimum period of sixty (60) months from the originally scheduled date of payment, provided that such election to delay payment (a) is made at least twelve (12) months before a scheduled date of payment and (b) is not effective until at least twelve (12) months after the date on which the election is made.

The Participant may, at the same time the date of payment is re-deferred, change the form of payment provided that such change in the form of payment does not effectuate an acceleration of payment. Notwithstanding any provision contained herein to the contrary, a distribution made to a Key Employee due to his Separation from Service (for any reason except due to his death) shall not be made before the date which is six (6) months after the date the Key Employee has a Separation from Service unless otherwise permitted under Code Section 409A, such as in the event of his death.

Unforeseeable Emergency. A Participant may request a distribution due to an Unforeseeable Emergency. The request must be in writing and must be submitted to the Administrator along with evidence that the circumstances constitute an Unforeseeable Emergency. The Administrator has the discretion to require whatever evidence it deems necessary to determine whether a distribution is warranted. Whether a Participant has incurred an Unforeseeable Emergency will be determined by the Administrator on the basis of the relevant facts and circumstances in its sole discretion, but, in no event, will an Unforeseeable Emergency be deemed to exist if the hardship can be relieved: (a) through reimbursement or compensation by insurance or otherwise, (b) by liquidation of the

Cashouts of Minimal Interests. If the amount credited to the Participant’s Account does not exceed the current dollar limitation under Code Section 402(g)(1)(B) ($17,000 in 2012, as adjusted under the Code in future years, or such higher dollar amount as Treasury Regulations may establish for cashouts of minimal interests under Code Section 409A), at the time he has a Separation from Service, and such Participant is not a Key Employee, the Company reserves the right to pay such amount to the Participant in accordance with the requirements of Code Section 409A in a single lump-sum cash payment within ninety (90) days following such Separation from Service, regardless of whether the Participant (i) had made a different election regarding time or form of payment or (ii) was receiving installment payments at the time of Separation from Service. In the case of a Key Employee, such cashout payment shall not be made before the date that is at least six (6) months from the date of his Separation from Service or such earlier date upon which such amount can be paid under Code Section 409A without being subject to taxation thereunder.

Distribution to a Key Employee. Notwithstanding any provision of the Plan to contrary, any lump sum or installment payment distribution payable to a Participant who is a Key Employee due to his Separation from Service (for any reason except due to his death) shall not be made before the date that is six (6) months after the date of his Separation from Service.

Amendment by Company. The Company reserves the right to amend the Plan through action of the Board. An amendment must be in writing and executed by an officer authorized to take such action. Each amendment shall not be effective prior to approval by the Board in its resolution, unless necessary to comply with applicable laws or regulations.

Effective August 8, 2019, in addition to amendments made by the Board, the Chief Executive Officer of the Company or other officer designated by the Board (the “Authorized Officer”), may approve, adopt and execute any amendment to the Plan that is necessary for purposes of legal compliance, to clarify ambiguities in the Plan document, and to simplify non-material administrative processes, as the Authorized Officer may, in his best judgment, so determine; provided that the Authorized Officer may not terminate the Plan. The Authorized Officer may delegate to another officer of the Company or Occidental Petroleum Corporation the

Retroactive Amendments. An amendment made by the Company in accordance with Section 8.1 may be made effective on a date prior to the first day of the Plan Year in which it is adopted if such amendment is necessary or appropriate to enable the Plan to satisfy the applicable requirements of the Code, ERISA or to any other change in federal law or to any regulations or ruling thereunder.
